How Do Cigar Humidifiers Work – Complete Guide

Certain things get better with age and fortunately a good cigar is one of them. However, a cigar that's kept too damp or dry and is stored in a too warm or cold space will not burn at its peak flavor profile. To ensure that your favorite cigar doesn't lose its quality over time, you must store it in the most optimal environment.  

That's where a cigar humidifier comes in. Once your cigars are stashed away with a high-performing humidifier, they'll remain fresh and last for a longer time.


The main question here is: how do cigar humidifiers work? This post will walk you through everything you need to know about cigar humidifiers. Luckily for you, we have also listed our top three recommendations below. 

What is a Cigar Humidifier? 

A cigar humidifier is a component of a humidor that helps maintain a relative humidity level. A humidor itself is a storage box for cigars. It provides precisely controlled temperature and moisture levels for your cigar to thrive.

In fact, what distinguishes a humidor from any regular storage box is its humidification system. This system is maintained – all thanks to a cigar humidifier! Let's understand why it is so essential to maintain an optimal humid condition in the first place.

A fun fact about cigars is that they can expand and contract based on the relative humidity in their surroundings. This means that too much or too little moisture in the air is all it takes to impact any cigar negatively. In low humid levels, a cigar dries and shrivels up, resulting in cracking and loss of flavor or aroma. On the contrary, excess humidity tends to absorb water from the air. This ultimately leads to molds, rots, and even an infestation of tobacco beetles. 

Of course, nobody wants that. As a general rule of thumb, if you want your cigar to last for more than two weeks, buying a cigar humidifier is an inevitable option for you.

How Does A Cigar Humidifier Work? 

Now that you know the purpose of having a humidor as a cigar enthusiast, let's look at how it is achieved. 

As you must have already guessed, a cigar humidifier is a super-essential component of a humidor. It acts as a source or receptor for hydration. In other words, if the humidity level is low inside the box, a humidifier releases moisture content. Similarly, it absorbs moisture if the humidity level goes higher than optimal. 

The best humidity level for a cigar is 70%. 

All you have to do for your humidifier to work efficiently is to refill a cigar humidifier solution every once in a while! 

Cigar Humidifier Solution

A cigar humidifier uses a humidification solution as the hydration source. The refill frequency of this solution depends on the type of humidifier in use. The solution consists of 50% propylene glycol and 50% water. This secret potion is known for preserving flavors and aroma in your cigars.

Other than refilling the humidifier with this solution, you can also use it to season your humidor for added benefits. Here's how you can do it by following these two simple steps: 

  1. First, wipe the interiors of a humidor with distilled water using a soft cloth. Make sure it's only dampened and not entirely soaked with water. Keep the lid closed for a few hours.
  2. Soak a sponge with the cigar humidifier solution. Squeeze it up to remove the excess, and then place it inside the humidor for a while. Make sure that it is kept away from sunlight.

And just like that, this humidification process will prepare your humidor for taking better care of your cigars. It is recommended to season your humidor at least twice a year. 

Types of Cigar Humidifiers

Cigar humidifiers, along with other components of a humidor, play a critical role in maintaining humidity. Below we will talk about the three most common (and efficient!) types of cigar humidifiers.

1. Floral Form

It is often used in humidors, making one of the excellent cigar humidifier options. This is enclosed in a plastic container with ventilation spaces allowing the moisture flow. You need to replace the humidification solution every two weeks and the entire floral foam once at least in 6-12 months.

2. Crystal Gels

Crystal gel also works well as cigar humidifiers. It mostly comes in jars, and when water is poured over it, the gel absorbs it and expands. Next, this expanded gel is placed in a humidor to absorb or release moisture as per the requirements. Thus maintaining the humidity level.

The advantage of crystal gels over floral foam is that you have to replace the humidification solution once a month, and the gel can last as long as a year or two.

3. Electronic Humidifiers

This type of cigar humidifier works most proactively. That's because it can electrically detect the humidity levels, which makes its functionality rapid and precise. And as needed, moisture is added or removed from the humidor accordingly. It also ensures a more efficient humidification control than the last two types that need manual control instead. As for the refills, it mostly depends on how actively moisture content is being used up in a humidor.

Humidor Components (Other Than Humidifiers)

As mentioned above, cigar humidifiers are one of the many other components of a humidor. But the truth is that a humidifier cannot just work on its own to preserve the quality of a cigar. All the humidor's components work in harmony to ensure that it serves its purpose. Each of these is important in its own way, with one common goal – keeping the conditions inside the humidor cigar-friendly!

That's why it's important to learn about these other components as well.


A hygrometer is a device that can measure the amount of moisture in the humidor. This way, you can always know whether you have to add more humidification solution or remove some. This device can be either digital or analog.

All you've to do is check the hygrometer, preferably every fortnight, to ensure all is well inside the cigar humidifier. 


Most humidors have a thermostat that helps in keeping the temperature steady inside. Cigars remain fresh in temperatures as cool as 60-degree Fahrenheit or as warm as 72-degree Fahrenheit. In other words, cigars are best preserved at room temperature. 

If you think that's all a thermostat does, well, there's more! A thermostat also helps in keeping the humidity balanced. Warm air holds more moisture, while cool air is much drier. This means that humidity levels are also kept in check by maintaining the optimal temperature. 

Spanish cedar wood

Most cigar humidors come with interiors made up of Spanish cedar. It is a kind of wood used to make the walls, shelves, or drawers of the humidor. This is mainly because Spanish cedar is known for its insect-repellant and decay-proof qualities.

Moreover, it has water-absorbing and releasing benefits without risking the occurrence of rots and molds. Yet another way to keep the humid conditions even inside the box.

Thus, all these components work with the humidifier and qprovide an effortless, trouble-free solution for cigar storage!
